Question

find the some of the odd numbers between 0 to 50 ​

Answer 1

Step-by-step explanation:

1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49

Answer 2

Step-by-step explanation:

We can find the sum of odd numbers by using arithmetic progressions.

According to question,

a = 1

n = 50

d = 2

Now, formula for sum of 'n' terms of an AP:

S = (n/2) * [ 2a + (n-1)d ]

S = (50/2) * [ (2)(1) + (50-1)(2) ]

S = (25) * [2 + (49)(2)]

S = (25) * [2 + 98]

S = (25) * [100]

S = 2500

Hence, the sum of odd numbers between 0 and 50 is 2500.
